Outcome evaluation and cost-effectiveness analysis for an integrated multidisciplinary diabetic limb salvage program: a combined observational and simulation study.

Introduction: To compare the clinical outcomes and healthcare utilization of patients enrolled in the multidisciplinary Diabetic Foot in Primary and Tertiary (DEFINITE) Care program with a matched historical cohort and estimate the program's long-term cost-effectiveness using simulation.

Research Design And Methods: This study consisted of two components: a 1-year observational outcome evaluation and a long-term simulation-based cost-effectiveness analysis (CEA). We conducted an observational study to analyze 2798 patients with diabetic foot ulcers (DFUs) enrolled in the program between June 2020 and June 2021 (DEFINITE Care group) and 5462 patients with DFUs from June 2016 to December 2017 as historical controls.

Second Comment on 'Modeling for predicting survival fraction of cells after ultra-high dose rate irradiation'.

We comment on the reply by Shiraishito our comments regarding their recently published study 'Modeling for Predicting Survival Fraction of Cells after Ultra-High Dose Rate Irradiation'. While we appreciate the effort of the authors to consider our comments, we see ourselves compelled to add another short comment as we believe that some of our suggestions have been misrepresented. This may have resulted in a misguiding re-evaluation of the model.

Mitigating mitochondrial dysfunction and neuroinflammation by hematoma aspiration in a new surgical model for severe intracerebral hemorrhage.

Background: Intracerebral hemorrhage (ICH) is associated with a large hematoma that causes compression, increased intracranial pressure (IICP), midline shift, and brain herniation, and may ultimately lead to death. Urgent surgical removal of the large hematoma can ameliorate these injuries, which would be life-saving, but has not improved clinical outcome. A suitable animal model that mimics the clinically relevant human severe ICH injury requiring surgical hematoma evacuation is urgently needed.

Oxygen consumption measurements at ultra-high dose rate over a wide LET range.

Background: The role of radiolytic oxygen consumption for the in-vitro "Ultra-High Dose Rate" (UHDR) sparing and in-vivo FLASH effect is subject to active debate, but data on key dependencies such as the radiation quality are lacking.

Purpose: The influence of "dose-averaged Linear Energy Transfer" (LETd) and dose rate on radiolytic oxygen consumption was investigated by monitoring the oxygen concentration during irradiation with electrons, protons, helium, carbon, and oxygen ions at UHDR and "Standard Dose Rates" (SDR).

Methods: Sealed "Bovine Serum Albumin" (BSA) 5% samples were exposed to 15 Gy of electrons and protons, and for the first time helium, carbon, and oxygen ions with LETd values of 1, 5.
